[frontier] Why does my agent fail on mobile layouts or ultrawide monitors when it works fine on standard screens?

Implement normalized coordinate systems with aspect-ratio bucketing: train or prompt with normalized coordinates \(0-1 range\) and explicitly tag the aspect ratio bucket \(mobile/portrait/desktop/ultrawide\) in the context.

Journey Context:
VLMs trained predominantly on 16:9 screenshots develop spatial reasoning biases. When faced with mobile \(9:16\) vertical layouts or ultrawide \(21:9\) screens, coordinate predictions drift because absolute pixel coordinates \(x,y\) don't translate across aspect ratios. An agent trained to click at \(960, 540\) on 1920x1080 will miss completely on 1080x1920 mobile if it outputs the same coordinates. The frontier pattern abandons absolute coordinates for normalized coordinates \(0.0-1.0 range relative to screen dimensions\) combined with explicit aspect ratio 'bucketing' in the prompt \(e.g., 'This is a mobile portrait view'\). This forces the model to maintain separate spatial reasoning contexts for different layout geometries, preventing the 'aspect ratio blind spot' where the model assumes all screens are desktop landscape.
